What is a ceramic tile PEI rating and why is it useful to me?
The PEI (Porcelain Enamel Institute) rating is a 0-5 rating used to determine the abrasion resistance of ceramic tile. Here is a brief breakdown: PEI 0 – Very little abrasion resistance and is only recommended for walls or other no-traffic areas. PEI 1 – Recommended for very light traffic residential areas where hard bottom slippers and shoes will not be worn. PEI 2 – Recommended for light traffic residential areas where shoes are not worn. PEI 3 – Recommended for medium traffic areas. Tiles with this rating are usually okay for walking on in shoes, but they are not recommended for rooms with outside access. PEI 4 – Recommended for medium-heavy traffic area, these work well in most areas of the home including those with outside access. PEI 5 – Suitable for high traffic areas, this type of tile is the most durable.
